I do not limit myself to the exact construc tion and arrangement shown and described, as it is obvious that the working parts of the apparatus maybe changed, as a series of levers may be substituted for the cord, as shown in dotted lines in Fig. 1, without departing from the essential feature of my invention, which is the supplying the tool with a polishing or abrading material by its own motion at the will of the workman.

Having described my invention, what I claim, and desire to secure, is-

1. In a device of the character described, the combination of a supplyreceptacle, a polishing-tool above it, a lever pivoted upon the receptacle, a revolving server journaled in one end thereof adjacent to the said tool, and a shield supported upon the lever above the server, substantially as shown.

2. In a device of the character described, the combination of a supply-receptacle, a polishing-tool above it, a revolving server below the tool, and a shield havingone end extending over the server and its opposite end pivoted to a support, substantially as set forth.

3. In a device of the character described, the combination of a supply-receptacle, a polishing-tool above it at one end thereof, a rod pivoted between its ends above the receptacle and at the opposite side of the tool from the operator, a revolving server journaled in the end of the rod adjacent to the tool, a treadle at the same end of the receptacle as the polishing-tool, and a connection between the treadle and the opposite end of the rod from the scrveigwhereby the tool is moved vertically in relation to the tool by the treadle, substantially as described.

4:. In a device of the character herein described, the combination of a supply-receptacle, a tool above it, a rod having laterally-extending journals, a revolving server journaled in the end of the rod adjacent to the tool, and a shield having one end extending over the server and its opposite end pivoted upon the said laterally-extending journals, substantially as shown and described.

5. In a device of the character described, the combination of a snpply-receptacle,a polishing tool above it, a rod pivoted between its ends above the receptacle, a server journaled in one end of the rod below the tool, a stirrer within the receptacle below the rod and which is operated by the rod, and a means for operating the rod, substantially as set forth.

In testimony whereof I allix my signature in presence of two witnesses.
